` IMPRovEMENT iN MACHINES Een oREsslNe YARN on Termino.`

iBheSchedule referred to in these Letters Patent and `making of the same.

To all wroia ct ma/y concern Be it known that I, Gum JAQUITH, of Wes Concord, in the county of Middlesex and State of Massachusetts, have "invented new and useful Im `proveinen'ts in Machines for Dressing Yarn orflh read and vI do hereby declare that the following i is a full,

i elear,"and exact description thereof', which `will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part ot this specication. y

This inventiouurelates to animproved `means of dressing yarn toremove the foul matter incorporated with itriuworkingitup fromthe cotton, andconsists in lthe application, preferably to the spooler, when i Ithe `yarn-is all handled by separate threads, of corn `cobs'in-a `way to cause thethreads `to bedrawn over `the `roughened surfaceto separate the' foul matter.

Ipropose` to use thecobs Aalso in all other applications in which it may be useful in dressingv yarn.

Figure 1 representssome-,of the partsof a spooler i in elevation, showing-.one application' of the corncob's Figures 2 and 3 are front and side elevations of -a bracket4 having cobsappliedto it, and adapted tobe atiiachedto the traversing guide-rail; and4 Figures 4 and 5 show .modiiications of the manner of attaching 4the cobsr.` 1

Similarv letters of reference indicate* corresponding .l ,thefspool on'which` the yarn is tobe wound;

l" anda., y

O `D- `are the corn-colis, `over which the yarn is passed,` so asito lie-scraped and dressed by them on all sides. fAny other preferred or suitable arrangement of fthejcobs. may be used, and they may be apy Y pligdto'auy othermachine `,used in the manufacture of orfor dressing thread.l

" The cobs may be supported on a bracket, E,'at. tached `tothe guide-rail, and arranged so that the 4threadpasses over one and under the other.'

The cobs maybe split into small strips, Gc, and atmany pieces of cob, and tted so asto be adjusted ou their supports from time to time, to bringnewpieces into action as others become worn out.

When the cobsor sections thereof are used-#they i maybe arrangedon enter supports, which will admit themfto` be turned from/time `to time, as shown in figs,

` 4 and 5.

In' the processor' manufacturing cloth therehas always been experienced a difficulty arising from the foreign' substances inthe raw fibrous cotton.

To obviate. the evil there have been various machines constructed, such as the cotton-gin, millows, pickers, dirt-boxes, 85e., but, after all, there is a kind of .light substance, whichl I am unable .t'o describe, that passes'through all of the processes and becomes partially incorporatedwith thethread. Thisincorporation is consummated on the spin ning when the twist is first put into the yarn, andthen wound onto the Vbobbin. A Y

The next operation is to spool the yarn from the bobbin onto thespo'ols,"which hold about ten times as much yarn as the bobbius During this spooling process there is considerable of this dirt rattles oif. In this last process the yarn is 'all handled by separate threads, so that if' one-thread breaks there is but one thread stopped. N

`The next'process is to warp it. Here there are all the way from one hundred and seventy to three hundred threads run onto oneA beam, so that if a thread breaks in this l process it stops from one. hundred and seventy to three hundred threads, as the case may be. The beams 's o formed'` onthe warp'er, and which are called, after being fitted, section beams, are then pnt onto the dresser, and eight'of these beams run into one, called the center beam,so that if a thfead breaks here or, a stoppage occurs, there are-stopped from one `thousand three hundred and sixty to two" sized by the application of a glutinous substance made mostly of starch.` -By this sizing process'the yarn isv made hard, and the small items of foreign substances' attached to the thread become hard and somewhat, sharp. The center beam thus sized is ready forthe loom, after having been drawn into the harness and reed. t

Here comes the great exil. Everytime the harness isrpriln'g one half of the threads'are raised up and the other half down, so as to leave a-space of about two and one-halforthree inches for the shuttle to pass through witlithe lling. These threads, being in `such close proximity to each other, frequently catch each other by means of these hard little bunches or blighted seeds on the yarn, and thus cause such strain as to break the thread; pr, if .it does not break v this thread, it causes a drawnj'br sort of cockled place -ip 4thecloth. I believe thatif the breaksarisingfrom this" source couldbeobviated the production ofthe 'looms would be increased ten per cent.

, The object of my'invention 4is to take this foreign matter out on the spooler when the yarn is all handled by separate threads, and a single breakage-stop )pnt Aon the thread, and this I propose to accomplish Vby the use of the cobs herein described, which I have found by practical test to be fer the best substance for the purpose yetdiscovered. v

Thetough, hard, and rough exterior of the cob resists the wearing or cutting of the thread when drawn over it, and retains its sharpness,by which it removes the lumps o f dirt for alt-great length of time, .much longer-than any other substance.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The combination of eorn-cobs with spooling or other machines used in the manufacture of thread for trimming and dressing it, substantially in the manner described.
